Kevin Owens just wasn't the name that fans were expecting. Here are a few reasons why Owens took Adam Pearce's spot at the 2021 Royal Rumble Universal title match against Roman Reigns..@FightOwensFight challenges @WWERomanReigns for the #UniversalTitle in a #LastManStanding Match at #RoyalRumble! https://t.co/wzIAy9otwH pic.twitter.com/zHLVAsLSVb— WWE (@WWE) January 16, 2021#5 To finish up the Roman Reigns-Kevin Owens feudRoman Reigns and Kevin Owens at TLCRoman Reigns and Kevin Owens have only been feuding for all of December, and have resumed their rivalry in January. It wasn't a prolonged feud, but one that has an unfortunately predictable outcome.It isn't necessarily a bad thing, since most WWE fans would agree that Roman Reigns is more deserving of a Universal title reign now than Kevin Owens is. This has also been The Tribal Chief's longest World Championship reign yet.So far, they've had a TLC match and one inside a Steel Cage on the Christmas Special edition of SmackDown. Their third encounter will also have a stipulation - being a Last Man Standing match.It should be a fun one to watch, and it's actually the second year in a row where Roman Reigns will be having a stipulation Match at the Royal Rumble PPV. Last year, it was a 'Falls Count Anywhere' against King Corbin.WWE's decision to go with Kevin Owens again was likely because they wanted to close the rivalry completely - which is ultimately expected to end with Roman Reigns getting his hand raised.However, the steel cage match didn't seem like a suitable ending to their rivalry. A Last Man Standing Match, however, may do just that.
